Solution:

(c) Given, average of first three friends = 15
⇒ Total score of first three friends = 15 x 3 = 45
Average of last three friends = 16
⇒ Total score of last three friends = 16 x 3 = 48
Total score of four friends = 45 + 19 = 64
∴ Score of first friend = 64 - 48 = 16
Hence, required percentage =

16/48

× 100 % = 33

1/3
